Trivia: This film is based on a true story; but, of course, much dramatic license is taken with the facts. For example, while the movie depicts Lola shot in the chest (either by Willie Boy or by herself), the real-life "Lola" was shot in the back by the posse that was chasing them. Also, while the movie depicts Sheriff Cooper gunning down Willie Boy at the end, the real-life Willie Boy committed suicide by his own hand.
